摘　　要：桓仁水电站位于浑江中游,处于辽宁省桓仁县城东北,是浑江流域第一期水电开发工程。主要结合观测资料,对近几年桓仁水库的水位、大坝水平位移、垂直位移进行了比较。结果表明:①2007-2011年水库无破坏运行状况,水库水位变幅未超过历史水位变化范围;②大坝各坝段近5年位移值及变幅呈正弦规律变化,夏季温度高,坝体向上游平移,冬季温度低,坝体向下游平移。对比表明:左岸挡水坝段位移比中部溢流坝段和4#以右的挡水坝段位移略小;③坝顶沉陷随气温呈正弦规律变化,夏季气温高,坝体上抬;冬季气温低,坝体下沉。对比表明:中间溢流坝段沉陷量比两侧挡水坝段沉陷量略大。Huanren hydropower station is located in the middle of the northeast of Liaoning Province. It is the development of the first period of Hunjiang River Hydropower Project. This paper combining with the observation data of water level, in recent years, Huanren reservoir dam horizontal displace- ment, vertical displacement are compared. The results shows： （ 1 ） The 2007 -2011 reservoir damage condition, reservoir water level does not exceed the range of historical water level. （2） The dam dam nearly 5 years of displacement and amplitude of sinusoidal variation, summer temperatures are high, the dam upstream of translation, the winter temperature is low, dam downstream translation. Results show that： the left bank of dam displacement than central overflow dam section and 4# to the right of the dam section shift slightly. （3） The subsidence is a sine rule changes with the temperature, the summer temperature is high, the dam raised; the low winter temperatures, the sinking. Results show that in the middle of overflow dam settlement than the two retaining dam settlement slightly larger.
